Blue Sea 4378 WeatherDeck Water Resistant Circuit Breaker Panel - 8 Position - Grey

The Blue Sea 4378 WeatherDeck Water Resistant Circuit Breaker Panel—8 Position is engineered for serious boaters and anglers who demand reliable electrical distribution in saltwater and freshwater environments. After years on the water, you know that a single electrical failure can ruin a fishing trip or compromise safety when you're far from the marina.

This weather-resistant panel consolidates circuit protection and switching in one compact, corrosion-resistant unit, giving you independent control over pumps, electronics, lighting, and auxiliary systems without fumbling with multiple switches or worrying about moisture intrusion. Built by Blue Sea Systems—the industry standard for marine electrical integration—the WeatherDeck panel features eight individual breaker positions housed in a grey, UV-stable enclosure rated for saltwater spray and humid deck conditions.

Each position accommodates a 12–48 VDC circuit breaker, allowing customizable amperage ratings per circuit; thermal-magnetic breakers respond instantly to overloads while protecting connected systems from shorts and spikes. The compact 6 × 5 × 11-inch footprint weighs just 1.7 lbs, making it ideal for center consoles, offshore sportfishermen, and galley installations where space and weight matter.
